Check Digit Verification of cas no

The CAS Registry Mumber 1255101-69-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,5,1,0 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1255101-69:
(9*1)+(8*2)+(7*5)+(6*5)+(5*1)+(4*0)+(3*1)+(2*6)+(1*9)=119
119 % 10 = 9
So 1255101-69-9 is a valid CAS Registry Number.

supporting information; experimental part, p. 5287 - 5289 (2011/02/21)

The synthesis of unsymmetric functionalized pentacenes from 1,4-anthraquinones and functionalized isobenzofurans, which were prepared by transformation via C-H bond activation, was successfully accomplished. Examples of the synthesis of pentacenes with functional groups at the 5-position are still rare. These obtained functionalized pentacenes are highly soluble in hexane, toluene, and THF.
